Physicists can predict the jumps of Schrödinger’s cat (and finally save it)

Yale researchers have figured out how to catch and save Schrödinger's famous cat, the symbol of quantum superposition and unpredictability, by anticipating its jumps and acting in real time to save it from proverbial doom. In the process, they overturn... Continue Reading →

Breakthrough in new material to harness solar power

The most affordable, efficient way to harness the cleanest, most abundant renewable energy source in the world is one step closer to reality. The University of Toledo physicist pushing the performance of solar cells to levels never before reached made... Continue Reading →

Subsonic Turbulence

Most people are familiar with the notion of turbulence. Whether it is the chaotic swirls that appear as you add milk to your morning coffee, the branching and twisting of cigarette smoke that causes it to linger in front of... Continue Reading →

Researchers discover surprising quantum effect in hard disk drive material

Scientists find surprising way to affect information storage properties in metal alloy. Sometimes scientific discoveries can be found along well-trodden paths. That proved the case for a cobalt-iron alloy material commonly found in hard disk drives. As reported in a... Continue Reading →

Abel-prize winner Karen Keskulla Uhlenbeck built bridges between analysis, geometry and physics

U.S. mathematician Karen Keskulla Uhlenbeck has won the 2019 Abel Prize—one of the field’s most prestigious awardscfor her wide-ranging work in analysis, geometry and mathematical physics. Uhlenbeck is the first woman to win the 6-million-kroner (U.S.$702,500) prize, which is given... Continue Reading →

Bekenstein-Hawking entropy

The Bekenstein-Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to comply with the laws of thermodynamics as they are interpreted by observers external to that black hole. This is particularly true for the... Continue Reading →

The low-Reynolds-number gravitational settling of a sphere through a fluid interface

What is Reynolds number?The Reynolds number is an important dimensionless quantity in fluid mechanics used to help predict flow patterns in different fluid flow situations. Magmas typically consist of a mixture of molten liquid, bubbles, and solid crystals. As they... Continue Reading →

Shock waves interacting between two supersonic aircraft

This week NASA released the first-ever image of shock waves interacting between two supersonic aircraft. It’s a stunning effort, requiring a cutting-edge version of a century-old photographic technique and perfect coordination between three airplanes – the two supersonic Air Force T-38s and the NASA B-200 King...

The Surfactant-free Persistence of Surface Bubbles in a Volatile Liquid

Bubbles don’t stick around in pure water. Surfactants are needed to stabilize the thin liquid film for longer than the blink of an eye. But that’s not necessarily the case for other liquids. As the video below shows, a bubble in isopropyl... Continue Reading →
